Microwave imaging is a straightforward approach to detect scattering in a detected object. One application of microwave imaging is breast cancer detection, the most prevalent type of cancer in Indonesia and the leading cause of cancer-related deaths. The planar monopole antenna offers several advantages, including low bandwidth compared to microstrip antennas and a simple structure for easy and affordable fabrication. Metamaterial can be added to the antenna to operate within the ultra-wideband frequency range of 3,1-10,6 GHz. Metamaterial expands the bandwidth and offers advantages such as low fabrication costs and miniaturization potential. This study aims to design a planar monopole antenna with a hexagonal patch using metamaterial. The simulation results show a working frequency range of 3,0699 - 20,779 GHz, while the realized results are 2,6 - 11,3 GHz and 15,2 - 17 GHz. The simulated bandwidth value is 17,7091 GHz, whereas the realized bandwidth values are 8,7 GHz and 1,8 GHz. The return loss values are ≤ 10 dB and the VSWR values are ≤ 2. The gain at the frequency of 7,038 GHz is 1,963 dBi in simulation and 1,698 dBi in realization. Additionally, changes in electromagnetic parameters are observed when the antenna detects cancer.

Its necessary a technology or advanced device that can observe atmospheric data and send it to an earth station (ground segment). Data of information on air pressure, temperature, humidity, and wind speed are ordinarily needed by the Meteorological, Climatological and Geophysical Agency (BMKG) in weather forecasts. To be able to receive atmospheric data sent by the payload, the ground segment requires a receiver equipped with an antenna that has a big gain. The receiver is a transmission device which is equipped by an antenna. Double Biquad antenna is one of antenna with a big gain. Utilizing of the excellence specs of Double Biquad antenna, the author pick this antenna as a ground segment device that can support telemetry communication systems. The process of designing the Double Biquad antenna is carried out using an antenna calculator which is then simulated using 4nec2 software. The results of the antenna manufacture were tested and measured the antenna parameters such as: VSWR, impedance, radiation pattern and compared the RSSI value with Monopole on 3DR. The results show that the optimum frequency is 449.056 MHz with a VSWR of 1.33 which still meets the criteria of 1 ≤ VSWR ≤ 2. The value of the RSSI range on the Double Biquad antenna, 145 - 220, is better then comparison antenna. Coupled with the reflector which also strengthens the reception of power on the antenna. So this antenna is feasible to be used as a communication antenna in the ground segment which working on 433 MHz. Dibutuhkan sebuah teknologi yang dapat melakukan pengamatan data atmosfer dan mengirimkannya ke stasiun bumi (ground segment), tentunya dibutuhkan suatu perangkat khusus yang dapat melakukan hal tersebut. Data berupa informasi tekanan udara, temperatur, kelembaban, dan kecepatan arah angin biasanya dibutuhkan oleh Badan Meteorologi, Klimatologi, dan Geofisika (BMKG) dalam melakukan prakiraan cuaca. Untuk dapat menerima data atmosfer yang dikirim oleh payload, pada ground segment dibutuhkan suatu receiver yang dilengkapi dengan antena yang memiliki gain besar. Receiver tersebut adalah alat transmisi yang sering disebut dengan antena. Salah satu antena dengan gain yang besar adalah antena Double Biquad. Dengan memanfaatkan kelebihan yang dimiliki oleh antena Double Biquad penulis memilih antena ini sebagai perangkat ground segment yang dapat mendukung sistem komunikasi telemetri. Proses perancanagan antena Double Biquad dilakukan menggunakan antena calculator yang kemudian disimulasikan meggunakan software 4nec2. Hasil pembuatan antena diujicobakan dan dilakukan pengukuran beberapa parameter antena seperti: VSWR, impendansi, pola radiasi dan membandingkan nilai RSSI dengan antena pembanding (Monopole pada 3DR). Hasil pengujian menunjukkan nilai frekuensi optimum yang didapat sebesar 449,056 MHz dengan VSWR sebesar 1,33 dimana masih memenuhi kriteria 1 ≤ VSWR ≤ 2. Nilai rentang RSSI pada antena Double Biquad, 145 – 220, lebih baik jika dibandingkan dengan antena pembanding. Ditambah dengan adanya reflektor yang turut memperkuat penerimaan daya pada antena. Sehingga antena ini layak untuk digunakan sebagai antena komunikasi di ground segment pada frekuensi kerja 433 MHz.

Many types of antennas can be used for digital TV receivers; in this article we try to design a double biquad antenna. This is due to a simple form, easy to make, a wide beamwidth. In designing a digital TV receiver for the Malang area, an STB device is needed, so that analog TV can still receive digital TV broadcasts. In this study, the antenna is made of copper wire, each side length: ¼ ? , with a working frequency: 650 MHz. In order to match the impedance of the 75? coaxial cable with the antenna, a balun 4:1 is required. The research place is in the Polinema Telecommunications laboratory. The test results show that the lowest return loss (RL) occurs at a frequency of F=605 MHz, namely RL: -17.8 dB, for a frequency of F=650 MHz, the magnitude of RL: -11.3 dB. The large VSWR antenna at the working frequency F: 650 MHz is 1.46. So that it can be said that it has fulfilled the antenna parameters, namely VSWR < 2. It means that there is a power loss of less than 10%. The largest antenna gain occurs at a frequency: 400 MHz namely: 14.85 dB,. While the average gain of the antenna is 2.21 dB. The antenna radiation pattern is omni directional. The double biquad antenna is very good for use as a digital TV receiver for the Greater Malang area, either without using a reflector or with a reflector.
